"A lot of people want to be where we are with the opportunities God has given us, so to give back to the people who can't be where we are is a big thing for our team," Phillips said. "We're a serving team and look forward to brightening other people's days and have them look up to us with what we do to."

Phillips picked St. Jude as his charity of choice after watching his 3-year-old nephew, Jamar Fisher, endure multiple surgeries and chemotherapy treatment in his ongoing fight against brain cancer.

"A lot of young kids out there have certain types of cancers, and they can still do some stuff, but they can't do everything to their full potential because they have these things holding them back," he said.

An ankle injury limited Phillips to the 40-yard dash at this year's NFL Combine, so Wednesday's Pro Day gives scouts their first look at his ability to test well in drills like the vertical leap and the 20-yard shuffle.

"It was kind of hard watching people compete (at the Combine) knowing that I couldn't but I just had to make a business decision to wait for my time and not rush anything," he said. "My body's feeling much better, and I'm excited to come out and compete in front of the scouts since they've only seen me on film."
